Solution 3:
Some anti-virus program interfere with Cold Waters. This is often the case when sensors.txt is reported by the game as missing even though the file is there.
Add Cold Waters as an exception to your anti-virus software.

Solution 4:
Nahimic audio drivers may cause the game to not load when running from the Steam client. Disabling Nahimic and then running Cold Waters solves this.

Solution 5:
nv3dum.dll caused an access violation (0x0000005).
Reinstalling graphics driver's with a clean install and without installing the VR and 3D portions of the driver's solves this issue.

Solution 6:
Check your override directory. If a new update has been released you may be running a mod which is no longer compatible. Remove the override directory and if this resolves the crash, contact the mod author to let them know their mod requires an update.

Solution 7: Game takes 10-20 minutes to load
On some users' machines, the contents of the Windows Network Connections will include entries generated by third-party software such as LogMeIn Hamachi and VMWare. The Windows function that Unity uses to get the Proxy Settings for the user tends to hang for long periods of time if it encounters one of those third-party network connections. It's probably not able to get what it wants and just ends up waiting for a timeout. I suggest looking in Control Panel -> Network and Sharing Center to see if there are any network connections added by third-party software. If there are, try disabling them to see if it fixes the problem.

Not all Single Missions and/or Campaigns are listed
These are symptoms of an incompatible mod which usually occurs after an official patch breaks certain mods. Remove or update any mods/custom files from your override folder:
\Steam\steamapps\common\Cold Waters\ColdWaters_Data\StreamingAssets\override\

High GPU Usage Causes Hard Lock Up
In Options, ensure v-sync is on.
Also decrease the ocean complexity.

Known Issues
Mini-Map No Longer Works
It is possible to change the screen resolution or HUD scale in Options such that the mini-map no longer works or is incorrectly lined up in the bottom left panel. Simply go back into Options and click accept to re-calculate and correct the mini-map position.

Multiple Monitor Support
Multiple monitors are supported. You can also move all the HUD elements anywhere you want by mirroring hud/default.txt and modifying the [HUD LAYOUT] section in the bottom.

Check out the screenshots in the news article below. We had Cold Waters running on dual 27" 2560 x 1440 monitors and modified the HUD layout to put the elements on the left hand monitor with the tubes and panels nested against the mini-map.

In the file default/hud/default.txt are the parameters to move HUD elements around the screen as outlined below:
